자, 요약하자면, 저는 중견 규모의 Discourse 사이트(월 약 25만 뷰)를 운영하는 일을 돕고 있습니다. 서버의 대역폭/공간을 절약하기 위해 이제 백업과 업로드를 S3를 가리키도록 변경했습니다. 또한 현재 로컬에 저장된 약 6GB의 업로드 파일도 S3 버킷으로 마이그레이션하는 데 관심이 있습니다. 여기에서 제공된 몇 가지 가이드/지원 자료를 따라 봤지만, `rake uploads:migrate_to_s3`를 실행했을 때 몇 가지 실패가 발생했습니다.

현재 Digital Ocean VPS에서 호스팅되고 있습니다.

제 현재 상황과 매우 유사한 [Uploads migration to S3 fails](https://meta.discourse.org/t/uploads-migration-to-s3-fails/106487) 포스트를 발견했습니다.

launcher를 사용하여 앱에 진입한 후 실행한 (개인정보를 가린) 명령어 로그는 다음과 같습니다.

@vinothkannans님, 이 부분에 대해 팁이 있을까요?

몇 번 더 시도해 보았지만 성공하지 못했습니다. 진행하는 동안에도 여전히 동일한 오류가 표시됩니다.
